Mechanistic studies on prolyl-4-hydroxylase: the vitamin c requiring uncoupled oxidation Academic Article uri icon


  • A deuterated substrate for the human type I prolyl-4-hydroxylase was synthesized and its V/K deuterium isotope effect was determined to be 3.4 +/- 0.2. This isotope effect was attributed to the uncoupled oxidation. A dehydroproline containing tetrapeptide was also found to stimulate the uncoupled oxidation.
